Hearing Conservation for
Every Department, Every Crew.

Water plants, sanitation routes, parks crews, public works, and fleet shops. Public sector workers face industrial noise — and most cities still rely on a single annual van for half their employees.

The Reality on the Floor

Why Hearing Conservation Falls Through the Cracks in City Government

Distributed crews, fragmented EHS, inconsistent OSHA coverage, and shared budgets make hearing conservation one of the most over-promised, under-delivered programs in municipal safety.

Workers Are Scattered Across Departments and Sites

Water plants, treatment basins, parks crews, sanitation routes, fleet shops, and signal-maintenance trucks rarely share an EHS team. Each silo runs its own version of compliance — or none at all.

Landscaping and Sanitation Are Among the Loudest Jobs in the City

Backpack blowers exceed 100 dBA. Mowers, chainsaws, jackhammers, asphalt rollers, and refuse packers all run above the action level. Most municipalities have never run formal dosimetry on these crews.

Public Sector OSHA Coverage Is Inconsistent

In 26 state-plan states, public employees are covered by OSHA-equivalent rules. In federal-OSHA-only states, public sector workers may have weaker protection — but workers' comp, tort exposure, and union grievances still apply everywhere.

Audits Often Hit Multiple Departments at Once

When a state plan audits one department, gaps in another usually surface fast. A missing baseline in parks can trigger a citywide compliance review.

How Soundtrace Fits Into Local Government

Test at the Yard, the Plant, or the Garage

6 min

per test

Portable audiometric testing brings 6-minute tests to public works yards, water plants, and fleet garages. No more pulling crews to a single van location.

Cover Every Department on One Platform

All

departments unified

Water, sanitation, parks, public works, and fleet maintenance all in one centralized record. Per-department dashboards for fragmented EHS teams.

Verify HPD for Variable-Noise Field Crews

Real

NRR verification

Fit testing for line workers, mower operators, equipment operators, and refuse crews where noise varies hour to hour and standard NRR ratings overstate real protection.

Records Ready for State Plan, Council & Risk Pool Audits

30+

year retention

Centralized digital records for OSHA-equivalent state plan audits, city council oversight, and municipal risk pool reviews. 30+ year retention.

Know Your Exposure

Typical Noise Levels Across City Departments

Water/wastewater, parks, sanitation, and street crews all routinely exceed OSHA's 85 dBA action level — often without anyone in the city measuring it.

Compliance Context

OSHA & State Plans in the Public Sector

Public sector hearing conservation rules vary by state, but workers' comp and liability exposure do not.

26 State Plan States

Cover public employees under OSHA-equivalent rules including 1910.95 hearing conservation. CA, NY, MI, WA, and NJ are among the strongest.

Federal-OSHA Coverage Gaps

In federal-OSHA-only states, public sector workers may not be covered by OSHA itself — but workers' comp, tort liability, and union grievances apply universally.

Risk Pool & Council Oversight

Municipal risk pools and city council oversight committees increasingly require documented hearing conservation programs as a condition of liability coverage.

Workforce Exposure

Who Actually Needs to Be in the Program

City governments have the widest exposure variance of any sector — from quiet office staff to chainsaw and jackhammer crews. These are the roles that consistently land at or above the 85 dBA TWA action level.

Rollout Plan

What a Citywide Soundtrace Rollout Looks Like

Designed for fragmented EHS teams and multi-department budgets. Pilot first, scale department by department.

Phase 1Audit

Department Inventory & Dosimetry

Inventory exposure across water, public works, parks, sanitation, and fleet. Dosimetry on representative crews from each department.

Phase 2Pilot

Highest-Risk Department First

Baseline forestry, parks, or wastewater first — typically the highest-exposure team. Prove out the workflow before scaling.

Phase 3Rollout

Citywide Deployment

Roll out to all covered departments on a single platform with department-level dashboards for fragmented EHS teams.

Phase 4Ongoing

Annual Recertification

Annual rolling audiograms, state-plan-ready records, council-reportable compliance metrics, and risk-pool documentation.

Municipal FAQ

Common Questions From City Risk & EHS Leaders

Are my city employees actually covered by OSHA?
In states that operate an OSHA-approved State Plan covering public-sector workers (e.g., CA, NY, MI, WA, NJ, OR), municipal employees are covered by OSHA-equivalent rules including 1910.95. In federal-OSHA-only states, public workers may not be covered by OSHA itself — but workers' comp, tort liability, and union grievance exposure apply universally. We help map your specific state's coverage.
Can different departments be billed separately?
Yes. Soundtrace supports per-department cost centers with consolidated city-level reporting — useful for cities running parks, sanitation, and water on different funds or grants.
Does the program need to enroll firefighters and police?
Sirens are intermittent but can spike above 100 dBA. Most municipalities enroll certified-vehicle operators who are continuously exposed and exclude administrative staff. Soundtrace can model TWA based on duty assignment.
How do union grievances factor in?
Documented hearing conservation programs are a defense against grievances over hearing-loss claims. Centralized records also support contractually required exposure disclosure under most municipal collective bargaining agreements.
Will this satisfy our municipal risk pool requirements?
Most municipal risk pools and JPA insurers require evidence of an OSHA-compliant hearing conservation program for high-noise departments. Our exports map directly to standard pool documentation requirements.
Can records cover seasonal parks staff, summer hires, and contractor crews?
Yes. Seasonal and contracted crews are tracked the same way as full-time employees, with day-1 baselines and clear tagging for staffing-agency or contractor relationships.

Your City Never Sleeps.
Neither Should Your Hearing Program.
